Abstract (en)
[origin: EP0465308A2] An oven for bending glass sheets, comprising a number of heating cells, a station for bending by pressing, at least one cooling cell and a system for conveying the glass sheets stepwise. The glass sheets are placed on bending rings (2) mounted on movable trolleys (3) coupled to each other into a train. The train is drawn stepwise by a traction machine installed at the end of the oven and outside the latter. The driving point of the traction machine which drives the trolleys (3) stepwise and the length of the travel of this traction machine are controlled as a function of the temperature to take into account the variation in the length of the train. The accurate positioning of the trolley in the pressing station is obtained by means of a detector (27) combined with pivoting end-stops (28, 36). <IMAGE>
